Found it finally.....

Tested the ignition switch and it was fine but it was a very good guess.

After cutting a bunch of cable ties and unwinding a couple of rolls of electrical tape I found the culprit. Had a fried joint. I think what has happened is the +12v battery wire that piggybacks off the starter had shorted out due to some of the insulation melting from the hot headers. It was this wire that had cooked the join where it is spliced into the fuse\relay module. So I was still getting 12v when I tested, but as soon as some load came on it couldn't cope and dropped to millivolts.

Thanks for all the suggestions and certainly helped me track it down.

Now to put it all back together and design a heat shield for the starter\wiring. Ill post a pic up here once I come up with something.

Thanks again everyone for your input.
